THIS! I cannot stress it enough, how much this video has helped me understand the Substitution rule and come to grips with integrals in general. I love you
On the brink of failing the exam I stopped trying to guess and check and put all of my energy into understanding it and I finally understood it reverse chain technique (rct)
when he starts talking about "u boundaries not x boundaries" for the definite integral limits, why does "x=1 so u=2" and "x=2 so u=5"? Where do the 2 and 5 come from?
got it, its because he runs the x limit values through what 'u' equals (x^2 plus one) i.e (1^2 +1 = 2) and (2 ^2 +1 = 5). Just in case any one else asks the same question
You can treat du/dx as a fraction in certain instances, these instances have been proven to be true, but remember IT IS NOT A FRACTION. It just behaves like one sometimes that's all!
I used my textbook and my mind was spinning, but after watching this video, he cleared this concept up instantly. I'm glad I watched this.
yeah the textbook explanation for this is a dumpster fire
I owe all my knowledge of calculus to Eddie Woo. No one I know teaches it with the details and coherence he does.
Amazing how something that others find so difficult to explain can be so easy to this man. Beyond impressed
Hello Eddie Woo, I'm just letting you know that you still provide to the world for us
taking the class in 2020, thank you!

Sir, you are really great..........
Thank you for sharing your knowledge with all of us...............
as a 14 year old learning calculus, This was. to say the least, extremely helpful. Massive thanks.
you are a godsend, please never stop what you do
I am very thank ful to god that I know english and have shrap internet and thanks Eddie sir u are guruji(google it)love from india
I love this guy, but somehow the school bell distracted me and I’m not actually ending class, but it made me stop thinking about the maths 😂😂😅
There was a school bell?! I never noticed 😂 I wondered why he was speeding up at the end
On the brink of failing the exam I stopped trying to guess and check and put all of my energy into understanding it and I finally understood it reverse chain technique (rct)
thank u, ten times better than my previous teachers did
Love the way you teach man!, thank you!
eddie woo you have saved me once again
really a god gifted teacher!

@@Pollandland I wondered the same thing for a second and then, like you, "got it" haha.
Are the kids unpacking furniture behind the camera? I never understand why they're making so much noise. My calc class is so quiet compared to this 😂
you my friend just helped out with this video a lot of university students XD
I thought we couldn't treat du/dx as a fraction
well yes, but actually no...

@@alejrandom6592 That's calculus :)
Just wait until you get to quantum mechanics. "I thought particles were in only one place at any one time" 😂
So with an indefinite, u have to go back to your x, where with a definite, u can replace your x until you find the numbers.
how is he not famous!??😩
Thank you! I wish you were my Calc professor....
Very good in my opinion, thanks dude :)
Awesome teacher
شكرًا جزيلاً
Why at 4:25 did he say primitive of u^4 why the word primitive?
they probably say that in australia or something instead of "antiderivative". it kind of makes sense. good catch though, i hadn't noticed haha
nice way of teaching...:)
What if the x next to it dissapeared?
1:19 someone farted
Thank you so much sir
Sir I want know about soln of
Integration of 1/(5x-3) = ?
(1/5)*ln(5x-3) + c
this is incredible
Thank you! Really helpful video.
+1, thanks!!
My guy
Can you make more guitar videos? :)
Baller
oh my god thanks so much
sick bruh
Is this a real class? In what grade ? 😄 I saw one of this with 8 th grade math and now calculus .
he is the maths teacher of my high school and he is actually filming it in a class! so that 's the real class.
gg
Nice mate, your students were asking dumb questions tho, they in grade 10 or something?
Dumb questions don't exist, they're there to learn...
made me even more confused ffs
Yeah. 8 years later and I'd rather just remember all the reverse chain rule functions of integration than do all this.
